Hello, I am new here for my first betta fish, Blues. I got him about almost two weeks ago when I saw him sad and alone in the pet store. he has been living in 1g tank with 25w heater while I am preparing for his 5g home. Yesterday when I am ready to move him, I found white cotton thread like stuffs floating in the water and attached to his tail. So I rushed to pet store and bought fungus guard recommended by the store. I washed everything with hot water and changed/conditioned the water and put the medication in. The white things are gone and Blues seems more active. Today, the tank seems cloudy no more white stuffs and there is a giant poop(it is not food). And he spit out his breakfast (I feed him one at the time and he barely eat the first one) I have many questions and I am very serious about taking care of Blues. 1. How do I know the fungus is gone to transfer him to new home? 2. When should I use fungus guard again or change water? 3. Is the giant poop is because I feed him too much or he is sick? (The Tetra floating mini pellets says 3-4 twice a day and I have him 3 twice a day) 4. I will take couple pictures of Blues and I want to know if he has any other problems like fin rot or velvet (last night flash light shows gold skin on his belly) last picture is his new home and has been running for few days. Thank you so much for your time! I really don't want him to be sick!
